7. OPERATION

7.1 Flushing the Piping Assembly

A  newly  installed  piping  assembly  where  scale, 
sludge and other foreign matter are expected requires 
flushing  the  piping  assembly  before  commencing 
meter operation.
In order to safeguard the meter, use a bypass line for 
flushing. If there is no bypass line, install a short pipe 
section in place of the meter as shown in Fig. 7.1.

7.2 Operation Procedure

(1)  Drainage (in steam service):
 

To prevent steam hammer, drain the piping assembly completely.

(2)  Checking the meter for proper installation:
 

To ensure safety, inspect connecting bolts, gaskets, and other members for tightness and other conditions.

 

Make sure of the flow direction also.

(3)  Leak check:
 

Fill the meter with the fluid and check for any leak.

(4)  Turning power ON:
 

Upon completion of wiring connections, turn on power.

 

Verify that the receiving instrument does not register erratic counts with no flow.

(5)  Starting up the measurement line:
 

By starting up the pump or opening the valve, carefully allow the fluid to flow.

 CAUTION:  To safeguard the equipment connected, avoid a sharp increase in 

flowrate.

(6)  Operation check:
 

Verify that the receiving instrument registers the flow correctly.

 

Make  sure  that  the  fluid  conditions  (pressure,  temperature,  etc.)  and  flowrate  conform  to  the  meter 
specifications.
